Patient Demographics
From the 157 patients who underwent LAAC using WN devices, 16 (10%) underwent a combined strategy. Overall, the median follow-up was 13 months (IQR 25/75 3/24). The median follow-up was 13 months (IQR 25/75 4/24) for the single group and 5 months (IQR 25/75 1/24) in the combined group (p=0.1). The median age was 76 (IQR 25/75 71/80) and 71 (IQR 25/75 61/73) in the single and combined strategy groups respectively (p<0.01). The CHA2DS2-VASc score (mean ± SD) was 4 (IQR 25/75 3/5) in each group, whereas the HAS-BLED score was 4±1 and 3±1 respectively (p=0.03). Atrial fibrillation was permanent in 47 % of patients in the single procedure group and in 37% in the combined strategy (p=ns). Indications for LAAC are depicted in Table 1.
